GHAPPcast: Lifestyle and Nutrition Interventions for Constipation

July 2025

In this episode of the GHAPPcast, Kate Scarlata, RDN, a nationally recognized GI-focused dietitian, joins Amy Ladewski, PA-C, from Northwestern Medicine, to explore personalized, evidence-based dietary strategies for patients with Irritable Bowel Syndrome with Constipation (IBS-C). Using a real-world case study approach, they discuss the impact of fiber choice, the role of psyllium versus fermentable fibers like wheat dextrin and inulin, and how over-supplementation can worsen IBS symptoms. Kate provides practical, patient-friendly tips on how to reduce symptom-triggering foods without overwhelming dietary restrictions, highlighting how to reintroduce safe, low-FODMAP options without using the term "FODMAP." The episode also compares the benefits of kiwi fruit versus prunes, addresses common dietary missteps, and emphasizes the need for a gentle, individualized approach to fiber and food intake. Amy and Kate discuss when to escalate care with pharmacologic therapies, how to identify pelvic floor dysfunction, and why partnering with GI dietitians and psychologists is key to long-term success. For APPs treating patients with IBS, this episode is full of clinical pearls, counseling strategies, and lifestyle interventions to improve outcomes.
